A few real questions. Nobody gets turned away for these. They decide which of two modes you start in: the full counting version, or Kitchen mode — same coach, same photos, no calories, no weights, no scores. Just what's in your fridge and what to do with it. You can switch either way any time.

These next two don't stop anything. They change how it coaches you.

4 slices turkey, 4 ham, 2 tortillas, some cheese
Logged. 540 kcal · 52 g protein That's your whole per-meal number in one plate. Heads up though: cheese is 5.8 g per 100 kcal. It's a fat that happens to carry protein. The turkey's doing the actual work at 20.
scale says 198.8, down 2 👀
Careful, that's one morning. Your ten-day trend is 201.7, falling about 0.3 lb/wk. Monday you were 205.3, so most of that 2 lb is just water leaving after the weekend. Nothing to do differently. Weigh again tomorrow.

It starts you on one number.

Grams of protein per 100 calories. Everything else is downstream of this one, so it goes first. It turns "eat less" into "swap that for this", which is a question you can actually answer standing in your own fridge at 10pm.

Send it pictures.

Photograph the block of cheese before and after and it works out exactly what left the plate. Same with a shared board, a takeaway container, or a pan of something.

Point it at your fridge, your freezer or one shelf of the pantry and it keeps the inventory, so "what can I actually make right now" has an answer that respects what you have, what you're allergic to and what you flatly won't eat.

Then it stops being about food.

Tell it what you trained and it counts — and it knows that a lifting day and a rest day are not the same day, so it stops asking you to eat like they are.

It also watches the clock. A protein-light dinner at six is a 10pm kitchen raid at six-fifteen, and it would rather say something at nine than grade you in the morning. It learns when you weigh in, not when a generic app thinks you should, and it stays quiet the rest of the time.
